Hi there! To find the answer to that question, we can write and solve a proportion. Set it up like this: 240/x = 60/100. This is because we're looking for the whole and we already know the part, which is 240. Cross multiply the values in order to get 24,000 = 60x. Now, divide each side by 60 to isolate the variable. When you do, you get x = 400. You can check this by dividing and then multiplying that quotient by 100. 240/400 is 0.6 and 0.6 * 100 is 60. That makes 60%. There. 240 is 60% of 400.
7.3 * 10^2= 730. Just move the decimal two laces to the right.
Converting to vertex form is actually pretty simple so I think you might find something to help you out here. :)

Answer:
The slope would be -2 with a y-intercept of (0, -3).
I hope this helped to answer your question.
The answer is $36.80
First you multiply 32 by 15 which you get $4.80
Then you just add it which you get the answer
